I have been dating my boyfriend for over three years now and we have only ever had one real issue in our relationship...I mean yes we have a normal couple issues...but my boyfriends sex drive is way lower then mine and after a certain point it becomes an issue (after a while I get frustrated and we get into a fight)...when we first started dating and having sex he could not get enough of me (I was his first and he was my first) but then after a while it just seemed like our sex life almost stopped (on average we have sex once a fortnight) Im 21 and my boyfriend is 22 and from what he has told me as a teen and young adult he had a high sex drive (self gratification) but after we started dating and for a while before it seemed to slow down...I love my partner and I wont leave him or cheat on him for my own sex drive but when the issue of sex is brought up im left feeling horrible about my self and no matter how many times he tells me it not me and that he is still extremely attracted to me I can't help but feel like Ive done something wrong (He gets frustrated when I tell him this after a certain amount of time and He says stuff like is sex the only thing you think about) (However he will later admit that he does have a low libido and says he will try to do something about it but then we just go back to the same routine)....I will admit that I have gain weight since we first started dating I'm 173cm and I weigh anywhere between 77-79 kg depending on the day.

He has also gained weigh and his newsiest reason for our lack of sex is that he hates the way he looks....I still find him sexy and attractive but he has always been fit and has put on a few kg. But before he used his weight as the issue it was were we lived (we lived with housemates) and he said he did not like doing that with other people around...and after we moved into our own place he was not in the mood....Im just worried that after he loses the weight he will have another reason for lack of sex..(He also has a vascular vain that maybe causing low testosterone and at one point that was another reason but he would not go and get a sperm count)

I know sex isn't what a relationship is about but to me it is a physical, passionate Expression on love..Im just so sick of being the only one to initiate anything and always getting rejected it seems like its Always when he wants it how he wants it or I just miss out....my ideal sex life would be once or twice a week and so far ive never said no but like said we only really have sex once a fortnight, and I just can't push away the feeling that its me, I know he loves me and he is always affectionate, he always tells me he loves me and kisses me and when I fall asleep he is always cuddle up to me or vise versa

I was just wondering if I was the only one who was in a relationship like this....Im just so sick of (excuse the pun) but being the man in the sex department.....I just want my loving passionate sex life back...and its not like I haven't tried different things (Ive brought sexy outfits, sex toys, gone out drinking with him, sexy photos, hell Ive even brought hand cuffs and watched porn with him) nothing seems to work....

has anyone got any ideas or am I the only one in a relationship like this or then again am I just overreacting....I know its a stupid question but im just so sick of feeling rejected I mean its got to the point I wont even initiate anything because I don't want to be rejected again (My boyfriend is willing to help me fix out love life but besides the weight loss I don't know what else he can do)
